Mammotl), of another about half-growu, of the Rod Doer, the 

 fossil llorsc, aud of a small rodent. 



The Author gives sections through Endsleigh Street and along 

 the southern side of Endsleigh Gardens, and shows that where tho 

 bones were found there was a distinct valley in the London Clay, 

 running in a direction nearly due north and south, the inclination 

 of the valley being towards the north. The London Clay reached 

 nearest to the surface towards St. Pancras Church and in Upper 

 Woburn Place, the total thickness of the overlying deposits and the 

 made ground there being only about 12 feet. 



Other sections, given along the southern sides of Tavistock and 

 Gordon Squares and through Gordon Street and the western side 

 of Gordon Square, show varying thicknesses of the deposits, over- 

 lying the uneven floor of London Clay, of from 16 to 21 feet ; the 

 greatest thickness here is found at the north-western corner of 

 Gordon Scjuare. 



Seeds were also discovered in a loam near the bottom of Gordon 

 Street, at the same horizon as that containing the mammalian 

 remains, and some shells were found in a band of sandy clay, 

 under a calcareous deposit, about halfway down the western side 

 of Gordon Square. 



The Author says that the deposits above the mammaliferous 

 loam overlying the London Clay in this area cannot be classed as 

 pust-Glacial river-deposits, but must be considered as of Glacial 

 origin. The animals, therefore, which evidently died on the old 

 land -surface where their remains were found, lived there early 

 in the Glacial Period. 



4. " The Morphology of StepJianoceras zhjzagy By S. S. 

 Buckman, Esq., F.G.S. 



Material which has come into the Author's possession throws 

 light on the developments of St&phanoceras zigzag^ and such deve- 

 lopments seem to supply missing links in the connexion of 

 Bathonian and Bajocian species. 



The xiuthor separates the developments of *S'. zigzag into three 

 series, aud discusses the allied forms of each.
